KA OKE MA waena o ka hili 'ana i ke kookoo hao chrome a me CK45..

1. ʻOkoʻa kila kila

• ʻO nā koʻokoʻo kila kila i hoʻopaʻa ʻia ʻo Chrome: ʻo ka like ʻole o ka hui kemika o ke kila bearing, ʻo ka ʻike a me ka hāʻawi ʻana i nā hoʻokomo non-metallic, a me ka hāʻawi ʻana i nā carbide he koʻikoʻi loa.ʻO ia kekahi o nā māka kila ikaika loa i nā hana kila a pau.
• CK45 kila chrome-plated koʻokoʻo: He kiʻekiʻe-koʻikoʻi kalapona structural kila, e like me ka Japanese standard S45C, ka American standard: 1045, a me ka German standard C45.ʻO kāna hiʻohiʻona ʻoi aku ka ikaika a me ke kū'ē i ka deformation ma mua o ke kila A3 maʻamau.

2. Nāʻano mechanical likeʻole

• Lawe i ke koʻokoʻo kila chromium-plated: Hoʻokō nui i ka maʻamau GB/T18254-2002 a me ka ʻaelike maikaʻi ʻo Laiwu Steel GCr15JD i kūpono i nā koi o nā mea hoʻohana i hoʻopaʻa ʻia.. ʻO nā koi maikaʻi oGCr15JDʻoi aku ka koʻikoʻi o ka ʻaelike ma mua o ka maʻamau GB / T18254-2002, a ʻo GCr15JD e koi i ka ʻike oxygen ≤10ppm , ʻO ka pae hoʻokaʻawale waena ma lalo a i ʻole like me 1.0, ʻoi aku ka paʻa o ka mana haku mele, ka lōʻihi paʻa a me ka ʻokoʻa nui ma mua o ka GB / T18254- 2002 maʻamau.
• CK45 steel chrome-plated bar: ʻO ka ʻōnaehana mālama wela i ʻōlelo ʻia no ke kila CK45 i ʻōlelo ʻia ma ka maʻamau GB/T699-1999 he 850 ℃ normalizing, 840 ℃ kinai ʻana, a me 600 ℃ tempering.ʻO ka hana i hoʻokō ʻia ʻo ka ikaika hua ʻo ≥355MPa.

Heʻokoʻa ka 3.Process

• Lawe i ke kookoo kila chromium-plated: 50 tons a ma luna o ka umu uila UHP hoʻoheheʻe ʻia he 60 tons a ma luna o ka umu ahi LF e hoʻomaʻemaʻe ana i 60 tons a ma luna o ka VD furnace vacuum treatment, alloy steel billet a i ʻole rectangular billet e hoʻolei mau ana (260mm×300mm, 180mm×220mm), lohi. hooluolu a i ʻole Hoʻopau ʻana i ka nānā ʻana a me ka mālama ʻana i nā huahana ʻōwili wela.
• ʻO CK45 kila chromium-plated koʻokoʻo: 40Cr/5140 kila e hoʻomaʻalili ʻaila ma hope o ke kinai ʻana.40Cr/5140 kila i maikai hardenability, a hiki ke paakiki i ka wa hooluolu i ka aila, a me ka deformation a me ka pohā o ka workpiece mea uuku.Eia nō naʻe, ma lalo o ke kūlana o ka hāʻawi ʻana i ka aila paʻa, hiki i nā ʻoihana liʻiliʻi ke kinai i nā mea hana me nā ʻano paʻakikī ʻole i ka wai, ʻaʻohe ʻike ʻia nā māwae, akā pono ka mea hoʻohana e hoʻomalu pono i ka wela o ka wai inlet a me waho ma muli o ka ʻike.
